Unmounted Fused Silica Plano-Concave Lenses, ARHS-YAG
Excelitas offers a broad selection of LINOS® unmounted fused silica lenses in various focal lengths and diameters, simplifying selection for UV and high-power optical applications. We use only premium materials from trusted manufacturers and maintain strict tolerances to ensure exceptional quality. Each standard lens includes a double-sided narrow-band anti-reflection coating optimized for the central YAG wavelength of 1064 nm to maximize transmittance. All lens types are also available with a high-quality, black-anodized, engraved aluminum mount.
Plano-concave lenses are supplied unmounted to facilitate flexible, custom integration into optical systems. These lenses provide precise optical performance for applications that require controlled beam divergence. The narrow focal-length tolerances ensure consistent system integration and reliable optical behavior. The high-power, narrowband anti-reflection coating on a fused silica substrate maximizes transmission at the fundamental Nd:YAG wavelength of 1064 nm and offers excellent laser damage resistance, with a high damage threshold and reliable performance under demanding conditions.
ZEMAX files are provided to streamline optical design and simulation. For customized specifications or higher-volume production, contact us to request a quote tailored to your technical requirements.
